Nortel Proprietary
Note:
The changes described below have been introduced in version 1.2 of the
Nortel Remote Agent Observe Planning Installation and Administration guide.
Switch Configuration Overview
The Nortel Remote Agent Observe card has 32 ports, 16 of which are configured as
Telephone User Interface (TUI) ports and 16 of which configured as Observe ports.
When a customer dials into the card, a Nortel Remote Agent Observe Session is
initiated.
Each Nortel Remote Agent Observe session consists of two ports: a TUI port and
an observe port. These ports must be established in pairs with the even number
ports (units 0, 2, 4, 6 etc) configured as TUI ports and the odd numbers ports (units
1, 3, 5, 7 etc) configured as observe ports.
An example configuration of two Nortel Remote Agent Observe sessions is:
Unit 0 as a TUI port with unit 1 as the corresponding observe port,
Unit 2 as a TUI port with unit 3 as the corresponding observe port.
This section highlights the changes required to
TUI ports
in the Nortel Remote Agent Observe slot.
Original TUI port configuration
Each TUI port was configured with an MCR (Multiple Call Ringing) Key. This
key specified the TUI Multiple Appearance DN (MADN) for the Nortel Remote
Agent Observe card. This MADN was used to dial into the Nortel Remote Agent
Observe TUI.
In this configuration, when an Observer dials into the Nortel Remote Agent
Observe Card using the MADN, the switch presents the new call to each idle TUI
port. The first TUI port to respond to the switch, receives the call and all other TUI
ports return to an idle state.
New TUI port Configuration
In the new configuration, a round robin approach to answering TUI calls is used
rather than the switch presenting a new call to all idle TUI ports, as occurs when an
MCR key is used. (See
Original TUI port configuration
above).
This is achieved by use of SCR keys and a mode of operation known as Hunting.
Hunting involves linking all configured ports into a chain of DNs.
How hunting works:

An observer calls the SCR key DN on TUI port 0.
